Finally no wild turning the thermostat more

I once bought a total of three of these regulators. A bathroom and two for my living room. I'm from the operation excited and I was actually really aware only after the purchase, what benefits you have with this thermostat. So I have it now nice and warm in the bathroom in the morning after getting up, even though I have not a bit heated at night, but just 30 minutes before getting up. Previously was the controller in the bathroom 3 and has permanently, even at night fully heated (we have district heating and I can all the heating system does not turn down at night). So I do think that a considerable saving can be achieved with it. Of course, not for people who anyway have a heater, where you can program a night set centrally for the whole house.

Overall, one can 3 hot and 3 cold phases (I call times) set per day. So from when to when it is eg. 23 ° C to be warm and from when to when is the radiator only concern when it comes eg. Below 19 ° C. All 6 phases can be configured with an individual temperature. One must also not be adjusted individually every day, because you have the option, for example. Mo-Fr. and Sat-Sun or Mon-Sun directly set level. This saves time during configuration.

I have using a Raumtherometer measured and watched, when I turn up in 0.5 ° C increments on the thermostat when the radiator starts the temperatures. This happens after the turn up but only a bit sluggish after 10-20 seconds. Then I had to give the thermostat using the offset 1.5 ° C and now I can really set 22 ° C on the thermostat and the room is heated when the temperature drops below 22 ° C. The offset can be of -3 ° C 3 ° C to + adjust what probably sufficient in each scenario.

The volume when the thermostat off or zuregelt is moderate. In the bedroom next to the head, it would bother me probably, but at night I would not walk there anyway heating. During the day it does not bother me. You can hear this sound even when the TV is in a normal voice, but you have to guess it then. Comparable perhaps when shutdown the electric roller shutter at a neighbor (townhouse). You hear it dull, but it does not bother really.

Toll is also the key lock on the thermostat. It can lock up all entries with one keystroke. I have two small children, so that's worth the function of gold. :-)

Setting everything can be great, comparable with electric blind control. Using the rotary knob for the temperature you can shimmy to the menu item and also adjust values ​​up and down and confirmed with OK you and breaks you from MENU. Everything is very well described in the manual.

A star deduction I admit that the "window open" function does not work for me. I have test times at 23 ° C room temperature, the window 10min tilted at approximately 9 ° C outside temperature and it heats and heats and continue to heat. The valve does not rotate to. In addition, the boost function is not mature for me. One can open the valve to 80% of a button, regardless of the room temperature for 300 seconds. For me it is so that nothing brings, because after 300 seconds, the heater is barely lukewarm and then goes again everything out. So felt (or not even felt :-) in my bathroom, the room temperature is raised by perhaps imperceptible 0.2 ° C by a boost throughput. There is also no way to increase 300 seconds to 600 seconds perhaps, what I miss. Thus, this function is useless to me.

4 stars anyway because I can recommend it to a) and b) its essential functions very well met and I will probably in the long run really save on heating costs. The price is unbeatable, incidentally, if the thermostat in 2 or 3 years should still prove me well.
